Loudness matching

摘要

An example method may involve a device determining a first loudness representation for a playback device based on a first equalization setting applied to a representation of average music. The device may also determine a second loudness representation for the playback device, based on a second equalization setting applied to the representation of average music. The device may also determine a loudness adjustment factor based on the first and second loudness representations, and then causing the playback device to play back media based on the second equalization setting and the determined loudness adjustment factor.

1. A device comprising:
a processor; a non-transitory computer-readable medium; and program instructions stored on the non-transitory computer-readable medium that, when executed by the processor, cause the device to perform operations comprising:
determining a first loudness representation for a playback device, wherein the playback device comprises a first equalization setting, and wherein the first loudness representation is based on the first equalization setting applied to a representation of average music, wherein the representation of average music comprises a power-frequency dropoff curve;determining a second loudness representation for the playback device, wherein the playback device comprises a second equalization setting, and wherein the second loudness representation is based on the second equalization setting applied to the representation of average music;determining a loudness adjustment factor based on the first and second loudness representations; andcausing the playback device to play back media based on the second equalization setting and the determined loudness adjustment factor.
